Hi
I'm starting new in the metal casting and just more of a hobby then anything else. I have built a home made foundry using the instructions available on internet with PoP and sand. I'm planning using styrofoam to carve some designs and pour molten aluminium on it over this weekend to make it sturdy.
My question is - What benefits does aluminium metal casting have over say papier mache or just using plaster of paris to create designs on its own. Apologies if the questions comes across as a layman question but as said earlier - Im pretty new to this .if someone can let me know what are the advantages of this - that will be awesome .
